Candidate: CVE-2009-0028
PublicDate: 2009-02-27

Description:
The clone system call in the Linux kernel 2.6.28 and earlier allows local
users to send arbitrary signals to a parent process from an unprivileged
child process by launching an additional child process with the
CLONE_PARENT flag, and then letting this new process exit.
Ubuntu-Description:
In certain situations, cloned processes were able to send signals to parent
processes, crossing privilege boundaries. A local attacker could send
arbitrary signals to parent processes, leading to a denial of service.
